Audiovisual distraction as an adjunct to pain and anxiety relief during minor surgery

BackgroundMinor surgery for ingrown toenails can provoke anxiety and the anaesthetic injection can be acutely painful. Distraction techniques may reduce the associated pain and anxiety.ObjectiveTo investigate an audiovisual distraction (Bedscapes™) on pain and anxiety during minor surgery for the correction of ingrown toenail.MethodIn a randomised controlled trial, patients (N = 152) with ingrown toenails requiring surgical correction under local anaesthesia were allocated to receive Bedscapes™ + standard care or standard care alone. Pain levels due to local anaesthetic injection were assessed post-procedure, and anxiety levels were assessed pre- and post-procedure in both groups. Follow-up focus groups were conducted with 14 patients allocated to the Bedscapes™ group, and one-to-one interviews were held with four podiatrists.ResultsParticipants with high pre-procedure anxiety scores experienced greater pain on injection, and older patients reported lower pain than younger patients, regardless of group allocation. Bedscapes™ did not reduce pain or anxiety, and was apparently no more effective than interpersonal interaction between podiatry staff and the patient.ConclusionsPain of injected anaesthesia correlates closely with pre-operative anxiety. Formal audiovisual distraction has no added benefit over interpersonal interaction in the alleviation of pain and anxiety in patients undergoing nail surgery.
